• Easy to Use: First, fully immerse the bubble air stone in water for 5-10 minutes, Then use a tubing to connect the stone and air pump. Finally, turn on the pump (for about 3 seconds) to test the airstone. If the bubbles are uneven, perform exhaust correction.
• Air Stone Disc: Size: 2.7" OD x 0.72" T. The air stone disc is well-constructed for easy, smooth and continual bubbling. Brush it regularly as it gets clogged after weeks or months of usage
• Medium Bubbles: The air stone always produces an abundant cascade of dense bubbles. Efficient bubbler for constant air diffusion, keeping your fish or plant roots growing healthily
